We obtained 6x600s clear-band frames with a median time of 2024-12-24T14:16:34, 10 hr after the EP trigger.\nNo uncatalogued optical transient is detected in the stacked images within the 3 arcmin EP/WXT error circle (Li et al., GCN 36405), down to 5-sigma limiting magnitudes of g ~ 22.5, calibrated with Pan-STARRS sources in the field. Also there is no apparent brightening for the catalogued sources within the error circle.\n",
